The corn has fallen down. Can you help it up? The old farmer said it depends on the situation.

Do you need to help up when the corn falls down? It depends on the growth period of corn, if it is lodging at seedling stage or before jointing stage, generally speaking, lodging is not particularly serious, but if lodging occurs after jointing or at the later stage of heading, try to help it up.

Maize lodging is a common problem in agricultural production. Improper cultivation measures, weak lodging resistance of varieties and field diseases and insect pests will appear large-scale lodging in the field when maize suffers from wind and rain disasters. Whether it will cause irreparable damage to the corn after lodging is a key criterion of whether it will cause irreparable damage to the corn. If the corn is not permanently damaged, then it is necessary to lift it, otherwise it is not necessary.

Pre-heading stage

At this stage, maize will also lodge, the performance is more serious is the jointing stage, when the plant is relatively tall, there will still be lodging harm in stormy weather. Generally speaking, the base of corn at this stage is fragile, and if it is forcibly picked up after lodging, it may cause the base to be broken. The loss outweighs the gain.

And the aboveground part of maize is still relatively light at this stage, if the lodging of the plant is not particularly serious (the angle between the plant and the ground is more than 45 degrees), it is not necessary to help it up, and the soil is cultivated at the base of the maize plant to prevent and control the secondary lodging.

After taking out the male

Generally speaking, when the corn completes the fertilization after heading, the weight of the ear will become larger and bigger. at this time, due to the heavy load-bearing of the ear after the lodging of the corn, the plant has lost the possibility of self-help to restore upright. Of course, a slight lodging, for example, if the angle between the corn plant and the ground is more than 60 degrees, there is no need to help it up. Because after all, the tilt of this angle, even if the corn can not return to upright, has little effect on photosynthesis and ear development in the later reproductive growth.

However, if the angle between the corn plant and the ground is less than 60 degrees, it is necessary to help it up. After all, with the development of the ear, the plant will bear more and more weight, and it may lodge more and more in the later stage, which may affect the yield.

The above analysis is only based on a general attempt, and it does not mean that it must be done, sometimes there is ambiguity between supporting and not supporting, but it is certain that once the lodging of corn is bound to affect the yield. Therefore, in the field management of maize, controlling prosperity and promoting rhizome growth and development are the problems that we need to pay attention to.
